Jujube slices were pretreated by cold plasma for 15, 30, and 60 s on each side, followed by hot air drying at 50, 60, and 70 °C. Scanning electron microscopy investigation indicated that the application of cold plasma significantly changed the surface topography of jujube slice by etching larger cavities, which can facilitate moisture transfer and consequently enhance drying rate and effective diffusivity. Modified Henderson & Pabis model and Two-term model were the two most recommended models for describing the drying kinetics of jujube slices. Cold plasma pretreatment improved the contents of procyanidins, flavonoids, and phenolics by 53.81%, 33.89%, and 13.85% at most, respectively, and thereby enhanced antioxidant capacity by 36.85% at most. Besides, cold plasma pretreatment can reduce the production of 5-hydroxymethylfurfural by 52.19% at most. In summary, cold plasma can be used as a promising pretreatment tool for drying processes of jujube slices.

The Atlantic wolffish (Anarhichas lupus) is a cold-water fish with potential for aquaculture diversification. To unveil the mechanisms underlying the compromised growth in Atlantic wolffish when reared at higher temperatures, we investigated the relationship between temperature, growth rate, aerobic capacity, stress biomarkers, and gut barrier function. Juveniles acclimated to 10°C were maintained at 10°C (control) or exposed to 15°C for either 24 h (acute exposure) or 50 days (chronic exposure).

Starch-lipid complexes have attracted widespread attention owing to high anti-digestibility and thermal stability. However, methods to increase the content of starch-lipid complexes are limited. Therefore, this study aims to investigate the effect of atmospheric cold plasma (ACP) treatment for different times (0, 1, 3, 5, and 7 min) on the formation and structure of complexes between maize starch (MS) and lauric acid (LA).

Fresh-cut apple slices (FAS) are prone to browning and microbiological safety issues. This study investigated the synergistic effects of cold plasma (CP) treatment and honey coating (HC) on preserving FAS quality during storage. Among six honeys, 10 % jujube honey exhibited the strongest anti-browning effect.

Suberin is an extracellular hydrophobic polymer deposited in seed coats that acts as a barrier to regulate the movement of ions, water, and gases, and protects seeds against pathogens. However, the molecular mechanisms underlying suberin deposition in the seed coat remain unknown. In this study, the in planta role of ATP-binding cassette G23 (ABCG23) was investigated in the Arabidopsis seed coat.

Understanding of the structure and interfacial merits that reactive metal-organic frameworks (MOFs) undergo is critical for constructing efficient catalysts for non-thermal plasma-assisted conversion of greenhouse gases. Herein, we proposed a free-standing bimetallic (Co/Ni) MOFs supported on bacterial cellulose (BC) foams (Co/Ni-MOF@BC) toward the coaxial dielectric barrier discharge (DBD) plasma-catalytic system, of which the Co/Ni ions coordination demonstrated an intriguing textual uplifting of the malleable BC nanofiber network with abundant pores up to micrometer-scale, which could impart a more intensive predominant filamentary microdischarge current to 180 mA with stronger plasma-catalytic interaction. Remarkably, compared to the monometallic MOF@BC foams, this bimetallic Co/Ni-MOF@BC also delivered a substantially improved alkaline absorption ability as further confirmed by the CO- temperature-programmed desorption (TPD) result.
